It is determined by how well timed that content material is and the way shortly Google must index and serve it in Google Search.
That doesn’t imply Google will not render the web page absolutely, it’ll, ultimately. But when a narrative is breaking and Google desires to indicate it in Google Search inside minutes of the story being printed, Google might need to return again later and absolutely render it later. Instantly, Google may course of the HTML after which come again and render the web page later to raised perceive the web page.
Listed below are these tweets from Gary Illyes on this matter:
it is a bit extra refined than “information does not render”. when you should index quick, you should have tighter deadlines and that may imply, for instance, that we find yourself with the uncooked HTML in serving for a couple of minutes. It she’s ultimately fixes itself, however nonetheless

It is a small technicality, however yea, ultimately Google will make an effort to render the web page and Google is just not gradual at doing that.
